Rick Warren son autopsy results confirm Matthew Warren died of suicide through a gun shot wound. The 27 year-old who suffered from depression and mental illness for most of his life, was found dead in his apartment on the morning of Friday, April 5.

"I'll never forget how, many years ago, after another approach had failed to give relief, Matthew said 'Dad, I know I'm going to heaven. Why can't I just die and end this pain?'" the author of bestseller "The Purpose Driven Life" said.

"You who watched Matthew grow up knew he was an incredibly kind, gentle, and compassionate man," Warren recalls.

"He had a brilliant intellect and a gift for sensing who was most in pain or most uncomfortable in a room. He'd then make a bee-line to that person to engage and encourage them."
